How to change oil ACURA TLX

Changing engine oil for a ACURA TLX car can be an overwhelming task for an unprepared person, and stretch out for a whole day. Although the work can be done in just 30 minutes. I’m here to share my experience and secrets with you! Let’s start with a few words about the car.

The Acura TLX first came onto the scene in 2014 as a midsize luxury sedan, intended to replace the TL and TSX in Acura’s lineup. Here in the US, we first saw it for the 2015 model year. The first-generation TLX offered three different powertrains: a 2.4-liter inline-four, a 3.5-liter V6, and a 3.5-liter V6 with a hybrid system. Acura gave it a refresh for 2018, introducing a new A-Spec sport variant and some updated tech.

The second generation of the TLX arrived for the 2021 model year, boasting a bold new design and some major updates under the hood. The base model now got a turbocharged 2.0-liter inline-four, and the high-performance Type S model came with a turbocharged 3.0-liter V6.

Internationally, the TLX got different names. In Japan, it’s known as the Honda Inspire. They’ve also sold it as the Honda Accord in some markets. But whatever you call it, it’s still that same sporty, reliable luxury sedan we’ve come to appreciate.

How to change engine oil on in theory

Changing the oil is critical because it keeps the engine running smoothly. It removes dirt and debris that can damage the engine and helps improve fuel economy. Regular oil changes prolong the life of your engine, saving you money on repairs in the long run.

So, let’s define the basic steps for performing a car engine oil change.

Warm up the engine to operating temperature

Drain the used engine oil and remove the old oil filter

Install a new filter and fill with fresh oil

Check the oil level with a dipstick

By following these simple steps, you can service your car. Now let’s take a closer look at each of the steps, select the recommended oil and filter. At the end of this page I will answer possible questions.

What you need to know before starting work

Frequency (interval) your Acura of engine oil change

For most modern cars like the Acura TLX, the manufacturer recommends changing the oil every 5,000 to 7,500 miles, or at least once a year if you don’t drive that much. Some high-performance versions might need more frequent changes. Always check your owner’s manual for the most accurate information.

How to check the level of engine oil

The engine oil dipstick is your tool for checking oil level. You’ll find it sticking out from the engine, often with a brightly colored handle. To check the oil level, first make sure your car is on level ground and the engine is cold. Pull the dipstick out and wipe it clean with a rag. Then, reinsert it all the way, pull it out again and look at where the oil line is.

There are usually two marks on the dipstick, one for “low” and one for “full”. The oil level should be somewhere between these marks. If it’s below the low mark, you need to add oil. If it’s above the full mark, you’ll need to drain some out.

A study conducted by General Motors (GM) in 1974 showed that lengthening the engine oil-change interval could reduce the frequency of automotive maintenance, the amount of oil required to service the car population, and the potential pollution problem resulting from the disposal of used oil.

Visual assessment of engine oil in a car engine

A rough way to judge the condition of your oil is to put a drop on a white paper towel and look at the color. New oil is usually amber and fairly transparent, while old oil will be darker and more opaque. If the oil is very dark, or if you can see particles in it, it’s probably time for a change.

What can (should) be changed at the same time with engine oil

  1. Oil Filter: Always replace the oil filter with every oil change.
  2. Drain Plug: Check the condition and replace if necessary.
  3. Drain Plug Washer: These are often overlooked, but they should be replaced at each oil change to prevent leaks.
  4. Air Filter: It doesn’t need to be replaced with every oil change, but it’s worth checking and cleaning or replacing if dirty.
  5. Check Brake Fluid: While not usually replaced with an oil change, it’s a good opportunity to check its level and condition.

Advantages and disadvantages of different types of engine oils for Acura TLX

There are three main types of engine oils: conventional, synthetic blend, and full synthetic.

Conventional oil is the cheapest, but it doesn’t provide as much protection against wear and doesn’t perform as well in extreme temperatures. It’s best for older engines or low-stress driving.

Synthetic blend is a mix of conventional and synthetic oil. It offers better performance and protection than conventional oil, but isn’t as good as full synthetic. It’s a good middle-of-the-road option.

Full synthetic oil provides the best protection and performance, especially in extreme temperatures. It also lasts longer, so you can go longer between oil changes. However, it’s the most expensive.

For a car like the Acura TLX, I’d recommend using full synthetic oil. It might be a bit more expensive, but it’s worth it for the increased performance and protection.

Necessary tools and conditions

For a successful oil change, you’ll need the following:

  • The correct amount and viscosity of engine oil
  • A new oil filter
  • Oil filter wrench
  • Socket set (for the drain plug)
  • Drain pan
  • Funnel (for adding new oil)
  • Clean rags
  • Car ramps or jack and jack stands (if needed to reach the drain plug and filter)

You should perform the oil change on a level, stable surface. Allow the engine to cool before starting, as the oil can be hot. Also, consider wearing gloves and safety glasses to protect your skin and eyes from oil. Always dispose of old oil and oil filters responsibly—most auto parts stores will recycle them for you.

Step-by-step instruction

How to warm up the engine Acura before changing the oil?

Before changing your oil, you should warm up your engine for a few minutes. This helps the oil thin out and flow better, making it easier to drain. However, you don’t want the engine to be too hot, as the oil could burn you. A short drive around the block should be enough to warm up the oil without overheating the engine.

Change engine oil with our own hands

Here’s a step-by-step guide to changing your oil. This process should take about an hour for beginners.

  1. Warm up the engine slightly (as mentioned above).
  2. Raise the car using ramps or a jack and jack stands, if needed.
  3. Place your drain pan under the oil pan.
  4. Use your socket set to remove the drain plug and allow the oil to drain into the pan.
  5. While the oil is draining, use your oil filter wrench to remove the old oil filter.
  6. Lubricate the gasket on the new filter with some new oil and screw it in place.
  7. Once the oil has finished draining, replace the drain plug and tighten it with your socket set.
  8. Use a funnel to add the new oil into the oil filler cap on top of the engine.
  9. Check the oil level with the dipstick and add more if needed.
  10. Start the engine and let it run for a few minutes, then check for leaks and the oil pressure light.

Possible questions after self-service FAQ

What problems can arise after an incorrect self-changing engine oil?

If the oil change isn’t done properly, a few issues could arise. You could have leaks if the drain plug or oil filter aren’t tightened properly. The engine might not get enough oil if you don’t add enough new oil, which could cause damage. And if you use the wrong type or viscosity of oil, it might not protect your engine properly.

How can I check for engine oil leaks after changing it myself?

After you change the oil, start the engine and let it run for a few minutes. Then, turn it off and check under the car for any signs of dripping oil. You can also check the ground under the car after it’s been parked for a while.

How to reset the oil change counter?

To reset the oil change light on the Acura TLX, follow these steps:

  1. Turn the ignition to the “On” position but don’t start the engine.
  2. Navigate to the oil life display on the dash using the steering wheel controls.
  3. Hold down the “Enter” button until the oil life resets to 100%.

Always refer to your owner’s manual for the exact procedure, as it can vary slightly between models and years.

What to do with old oil after replacement?

Used oil should be disposed of properly since it’s hazardous waste. Most auto parts stores and many recycling centers will take used oil and oil filters for free. Never pour used oil down the drain or onto the ground.
